# Release restriction

Releases all or part of the funds from an existing restriction by restricted funds ID.

NOTE:
- This endpoint requires an account token - an access token encoded with an external account ID. Tokens can expire quickly, which can result in a `401 Unauthorized` message.
This endpoint generates the following events:
- [Platform authorization created](https://developers.pismo.io/events/docs/platform-authorization-platform-authorization-1)
- [Account balance changed](https://developers.pismo.io/events/docs/availables-change-available-1)
- [Restricted Funds created or released](https://developers.pismo.io/events/docs/corporate-restricted-funds-1)
- [Account balance changed](https://developers.pismo.io/events/docs/account-balances-balance-change-1)

See [Data and reporting](doc:data-reporting-overview) for more information on events and setting up event notifications.
